The Trintella 29 represents a pivotal moment in the evolution of the Anne Wever shipyard, serving as the bridge between traditional Dutch steel craftsmanship and the modern era of glass-reinforced plastic (GRP). Designed by the prolific naval architect Ricus van de Stadt, the 29—often categorized alongside the Trintella I and IA models—is a classic long-keeled cruiser that embodies the "sea-kindly" philosophy of the 1960s and 70s. While many contemporary 29-footers prioritize internal volume and planing potential, the Trintella 29 was engineered for the challenging conditions of the North Sea, offering a heavy-displacement, S-framed hull that prioritizes stability and directional tracking over raw speed.

Sailing Performance & Handling
The sailing characteristics of the Trintella 29 are defined by its deep S-frame hull and substantial ballast-to-displacement ratio. With a displacement typically hovering around 3,800 to 4,000 kg, the boat possesses significant momentum, allowing it to punch through chop where lighter, modern yachts might lose speed. According to historical technical data from the Trintella Vriendenkring, the shipyard’s dedication to seaworthiness meant these vessels were often overbuilt, leading to a stiff sailing profile that rarely requires early reefing.
Under sail, the 29 is renowned for its exceptional tracking. The long keel and attached rudder provide a "hands-off" helm experience when the sails are properly trimmed, a trait highly valued by single-handed coastal cruisers. However, this underwater profile does result in a larger turning circle and less agility in tight marina berths compared to fin-keel designs. Owners frequently note that the boat excels on a reach or a beat in a Force 4 to 5 breeze, where its weight provides a sense of security and a dry ride.
Interior Comfort & Variations
The interior of the Trintella 29 reflects the "superyacht quality" that Anne Wever sought to bring to smaller production vessels. The layout is traditional, featuring a V-berth in the forepeak, a compact heads compartment, and a main saloon with two longitudinal settees that double as sea berths. The use of high-quality teak and mahogany joinery is a hallmark of the model, creating a warm, ship-shape atmosphere that has aged better than many of its more utilitarian contemporaries.
The Trintella 29 shares a lineage with several siblings. The Trintel I and II were the earlier steel-hulled predecessors, while the Trintella IA served as the direct GRP evolution. Buyers may also encounter the Trintella II, which offered a slightly longer waterline and increased beam, but the 29 remains the most sought-after for those seeking a "pocket" blue-water cruiser. Later variations of the 29 occasionally featured different galley arrangements, though most maintained the standard port-side kitchenette and starboard navigation station.
Known Issues & Buyer’s Checklist
Prospective owners should approach a Trintella 29 with an eye toward the specific maintenance needs of early GRP vessels and the high-quality wood finishes common to the brand.
- Deck Core and Teak: Many Trintella 29s were fitted with teak decks. Over decades, the screws used to fasten the teak can allow water to penetrate the sub-deck, leading to delamination or core rot. A thorough percussion test or moisture meter reading is essential.
- Engine Serviceability: The original builds often featured Farymann or Bukh diesel engines. While robust, these units may now suffer from parts scarcity. Potential buyers should verify if the vessel has been "re-engined" with a modern Yanmar or Volvo Penta, which significantly adds to the boat’s value and reliability.
- Chainplates and Rigging: Given the boat’s age, the stainless steel chainplates where they pass through the deck should be inspected for crevice corrosion. This is a common failure point on older Van de Stadt designs that have seen extensive offshore use.
- Osmosis: While the hulls were built with a heavy lay-up of fiberglass, early GRP can be prone to osmotic blistering. A hull inspection after the boat has been hauled for 24 hours is recommended to identify any "wicking" or blistering issues.
Community & Resources
The primary hub for owners and historians is the Trintella Vriendenkring, the official association for the brand. This organization maintains an extensive archive of original brochures, technical drawings by Ricus van de Stadt, and a registry of surviving hulls. Their annual meetings and technical wikis provide invaluable support for owners looking to restore these vessels to their original Dutch glory.
The Verdict
The Trintella 29 is an uncompromising traditionalist’s yacht, offering a level of build quality and heavy-weather capability rarely found in the sub-30-foot category.
Pros:
- Exceptional seaworthiness and stability in heavy weather.
- High-grade interior joinery and classic aesthetic appeal.
- Excellent directional tracking and ease of handling for solo sailors.
- Strong community support and historical documentation.
Cons:
- Heavy displacement results in sluggish performance in light winds (under 8 knots).
- Difficult to maneuver in reverse due to the long keel and prop walk.
- High maintenance requirements if the original teak decks are still in place.
- Limited interior volume compared to modern 29-foot "wide-beam" cruisers.
